Engineering cover letter: one project that proves you fit.
An engineering cover letter works best when it tells the story of one project that resembles the employer's work: the problem, your part, the method and the result. The resume covers everything else.
An engineering cover letter names the role and your discipline in the opening, then describes one project that matches the employer's work: the problem, your specific contribution, the tools or methods you used and the outcome you can document. Add a sentence on teamwork or standards, say why this company's projects interest you, and keep it to one page.

How to write it
- Open with role and discipline. The position, your field and your licence or certification status.
- Choose one matching project. The project closest to what the employer builds or runs.
- Describe your part precisely. What you designed, analysed or tested, with the method you used.
- State the outcome. What happened: built, approved, passed, improved, as you can document.
- Explain why this company. A project, product or market you have looked into.
- Close and sign. Offer to walk through the project in an interview.
